Severn Trent Water's latest water levels as reserves near half empty amid continued drought

Water levels at Severn Trent's reservoirs continue to decline as the 2025 dry spell continues across the country.

Published

Severn Trent's maximum reservoir capacity is 247,708 million litres, but the latest data shows the reservoirs are holding 132,680 million litres - just 53.6 per cent of their maximum capacity.

It's the lowest point the company's water storage capacity has reached since at least January 2023 - when the records begin online.

The lowest point last year saw water levels reach 69.7 per cent in September 2024, and 76.7 per cent the year before. 

The record low comes as provisional statistics from the Met Office show that summer 2025 will ‘almost certainly’ be the warmest summer on record for the UK - following what was the driest spring in over 50 years.

While temperatures have been a little cooler over the last couple of weeks, dry conditions have continued, with England seeing only 1mm of rainfall in the week end August 21. 

Over the next few days, it does look like the weather could turn, with the Met Office predicting "changeable and unsettled weather conditions" will bring showers or longer spells of rain across the majority of the country.

But whether or not it will be enough to officially take the West Midlands out of 'drought' status is yet to be seen.
